Two 5 molal solutions are prepared by dissolving a nonelectrolyte nonvolatile solute separately in the solvents X and Y. The molecular weights of the solvents are M_(x) and N_(y), respectively, where M_(x)=(3)/(4)_(y). The relative lowering of vapour pressure of the solution in X is 'm' times that of the solution in Y. Given that the moles of solute is very small in comparison to that of solvent the value of 'm' is

1.	Two 5 molal solutions are prepared by dissolving a nonelectrolyte nonvolatile solute separately in the solvents X and Y. The molecular weights of the solvents are M_(x) and N_(y), respectively, where M_(x)=(3)/(4)_(y). The relative lowering of vapour pressure of the solution in X is 'm' times that of the solution in Y. Given that the moles of solute is very small in comparison to that of solvent the value of 'm' is
Answer» `(4)/(3)` `(3)/(4)` `(1)/(2)` `(1)/(4)` Solution :RELATIVE lowering of V.P. `=(N)/(N)`]
